Mary Edith Collson (1870–1952) was an American feminist activist, Unitarian Universalist minister, and practitioner in The First Church of Christ, Scientist.
She went on to the Meadville Lombard Theological School in Chicago, where she was supported in her studies by Marian Murdock, Eleanor Gordon, and Mary Safford.
Upon graduation, she was encouraged to take a position with the Unitarian church in Ida Grove, Iowa.
She connected especially with the theology of the social gospel, and for a time she worked as a juvenile court parole officer at Hull House.
